激冷砂及其对铝合金铸件性能的影响

Chill Sand and It's Effect on the Aluminium Alloy Casting

论述了铝合金铸造用激冷砂的导热性及其对铝合金铸件组织、性能的影响，证实激冷砂是一种兼具金属型、砂型优点于一身的铸造铝合金铸件的优质砂。

This paper emphasizes thermal conductivity and the effect of chill sand on the microstrecture and property of aluminium alloy casting. It is proved that chill sand is one of the best molding materials for of aluminium alloy casting with the advantages of both ordinary sand and permament mold.\=
